Best Subreddits for Cybersecurity

Cybersecurity is the protection of computer systems from theft or damage and the avoidance of disruption or misdirection from the services the systems provide. With more and more people depending on information technology (IT) networks such as cloud computing, virtualization, and the internet of things (IoT) for online banking and shopping applications, the need to protect information security has become vital. Reddit’s structure allows information security and cybersecurity professionals to go deep into a subject in a way that is more natural than Telegram groups or Twitter threads. The website features many “subreddits”, which refers to sections of the website dedicated to specific topic areas. There are subreddits for almost every topic imaginable. Cybersecurity subreddits cover topics such as cybersecurity news, malware questions, penetration testing, and detection software. Some of the best subreddits for cybersecurity readers are listed below and covered in more detail later in this article.
